JOKE? No joke! Anyone in the fossil & shark biz knows meg poop when they see it. This comes from a diver in South Carolina that usually just picks up shark teeth in the Cooper River, St. John's and St. Mary's River beds.

The carcharodon megalodon lived during the Miocene Epoch - 23 to 5 million years ago.

Fossilized sharks teeth, vertebrae and occasionally coprolite (fossilized dung from which information about eating patterns in prehistoric times can be discovered) are found today. Megalodon reached a length of 60 feet or more.

This small cache of pyrite/marcasite coprolite was found in a small underwater cave/cut in the river. This is from a prehistoric "Spiny Shark" that presumably inhabited these caves/cuts and left their droppings to become fossilized. They have been replaced by pyrite/marcasite. Some of these still contain oyster shell fragments indicating that these sharks fed on them. The piling/mound twisting is caused by passage of the fecal material through a bone-like flap in the anus.
